29-11-2020· Useful heat value - Polytechnic Hub. UHV kcal/kg = (8900 -138)× {percentage of ash content + percentage of moisture content} In case of coal having moisture less than 2% and volatile content less than 19 %, the UHV value is arrived as above, reduced by 150 kcal/kg for each 1 % reduction in the volatile content below 19% fraction on
15-05-2018· The gradation of non-coking coal is based on useful heat value (UHV). The classifications are divided into seven grades from A-G. UHV is expressed in kcal/kg. UHV of grade –A non- coking coal is maximum (> 6200 whereas) grade –G has the lowest value of UHV (1300 – 2400).; UHV is an expression derived from ash and moisture contents for non-cocking coals as per the government of …
Useful heat value of coal = 8900 (M + Ash) Ultimate analysis gives fairly correct calorific value of coal and formula to be used is as below. GCV of coal in Kcal/Kg = (355 x C + 1148 x H + 95 x S 145 X O) / 4.1868; C, H, S, O are % figures obtained in the ultimate analysis of coal.
22-05-2021· Introduction. Before using the Fh value calculator, let's clear some basics. The F0 value calculator we've seen earlier helped us to understand the comparison between the ideal and actual exposure times. Therefore, it is named Equivalent Exposure Time (F0).Likewise, in dry heat sterilization, it is named in terms of heat i.e. Heat Penetration Factor denoted as Fh.
